Abstract

The present disclosure provides tissue webs with improved durability produced by rewetting a dried tissue web, pressing the rewetted web and drying the web for a second time. This improved durability is manifested by a high cross-machine direction (CD) slope.

Claims

exact text as granted — not AI-modified
We claim: 
     
       1. A tissue web having a CD tensile of less than about 1,500 grams per 3 inches, a CD stretch greater than about 12 percent and a CD slope greater than about 9,000 grams per 3 inches. 
     
     
       2. The tissue of  claim 1  wherein the CD tensile is from about 1,000 to about 1,300 grams per 3 inches. 
     
     
       3. The tissue of  claim 1  wherein the CD stretch is greater than about 15 percent. 
     
     
       4. The tissue of  claim 1  wherein the CD stretch is from about 12 to about 20 percent. 
     
     
       5. The tissue of  claim 1  wherein the CD slope is from about 11,000 to about 15,000 grams per 3 inches. 
     
     
       6. The tissue of  claim 1  wherein the CD tensile is from about 800 to about 1,500 grams per 3 inches and the CD slope is from about 9,000 to about 15,000 grams per 3 inches. 
     
     
       7. The tissue of  claim 1  wherein the web is a throughdried web. 
     
     
       8. The tissue of  claim 1  wherein the web is an uncreped throughdried web. 
     
     
       9. A tissue web having a ratio of CD slope to CD tensile greater than about 10 and CD Stretch greater than about 10 percent. 
     
     
       10. The tissue web of  claim 9  having a CD Stretch greater than about 12 percent. 
     
     
       11. The tissue of  claim 9  wherein the CD stretch is greater than about 15 percent. 
     
     
       12. The tissue of  claim 9  wherein the CD tensile is from about 1,000 to about 1,300 grams per 3 inches. 
     
     
       13. The tissue of  claim 9  wherein the CD stretch is from about 10 to about 20 percent. 
     
     
       14. The tissue of  claim 9  wherein the CD slope is from about 11,000 to about 15,000 grams per 3 inches. 
     
     
       15. The tissue of  claim 9  wherein the CD tensile is from about 1,000 to about 1,500 grams per 3 inches and the CD slope is from about 10,000 to about 15,000 grams per 3 inches.
